Currently it appears that only way that I can get my Blaze to update the time displayed is to delete it from my account and then pair it again. Following that the time will correct itself after a few succesfull syncs. I also have sync issues with my phone (Moto X Pure Edition), the majority of sync attempts fail (time out).
I have that set, (hence the title: "Auto Timezone set but not working") and it was working until about 6 weeks ago. Since then it won't update time unless I delete the Blaze from my account and pair it from scratch. Then only after a few successful syncs.
Best Answer@GaryScottMartin, sometimes the Fitbits get stuck on the wrong timezone. I am not sure why. if your Blaze is stuck on the wrong timezone it usually works to change it in the web based dashboard, rather than the app. You might find this simpler than re-pairing your Blaze.
Click on "Dashboard" -- there's a link at the top of every page in the Community forums. Then click on the gear icon (top right). Choose "settings" and scroll down to timezone and then update there. Be sure to scroll all the way to the bottom to save your changes. Then sync.
